In this work, we report the obtention of the LDH@Bi2WO6 heterostructure using an easy and low-cost method. The LDH was synthesized through the co-precipitation method with the metallic ratio of Mg2+/Al3+ = 2.0, while the bismuth tungstate nanoplates were prepared using the hydrothermal method. The LDH@Bi2WO6 heterostructure was obtained mixing LDH in water with 20 wt% of Bi2WO6. The LDH, Bi2WO6 and LDH@Bi2WO6 heterostructure were characterized by XRD, FTIR, N2 sorption, SEM, TEM, Raman, and DRS…

Synthesis, characterization and enhanced visible light photocatalytic activity of Bi2WO6/Ni–Al layered double hydroxide composites
Bi2WO6/Ni–Al layered double hydroxide (LDH) composites assembled from Bi2WO6 and Ni–Al LDH composites were prepared by a simple hydrothermal method. The as-prepared composites were characterized by
Nanostructured CeO2/MgAl-LDH composite for visible light induced water reduction reaction
Abstract Exploiting to enhance the visible light harvestation ability of MgAl-LDH, CeO2 have been dispersed over the surface of MgAl-LDH to design a series of CeO2(x%)/MgAl-LDH composite
Layered double hydroxides as efficient photocatalysts for visible-light degradation of Rhodamine B.
A series of Zn/M-NO3-LDHs synthesized by two different methods confirmed the formation of pure LDH phase with good crystal structure, and a possible mechanism for photocatalytic degradation on RB has been presumed.
